I like inches, I like the size of 1/8th" it’s suitable to my needs. I like the scale on the ruler, my eyes can instantly tell what I’m measuring because each tick is a different length. It works for me, it jives with my tools, I will not buy new rulers.

I would happily throw out all my drill bits and switch to numbered ones or metric, I don’t care. Fractions for hole size is dumb. I’ll also happily throw out all my imperial sockets and wrenches and switch to one kind of nut. Having two standards of the same tool just sells more socket sets. Which was probably the point.

If only they’d made a metre equal a yard, then everyone would be bilingual and we wouldn’t have to fight. You could use the one that was appropriate for the job.
